In the absence of an agreed national standard for the definition of grass fed, Overseer uses the terms of the draft AsureQuality Grass-Fed Standard to enable the definitions and sets a minimum criteria for feed management practices for the farming of bovine animals for dairy production.
The term “grass-fed” has a connotation of animals with daily access to pasture year-round; the standard promotes this whilst recognising that animal welfare is a priority and consideration must be given to environmental factors.
Every effort has been made to ensure that the terms of the standard are well represented within the software. Further information about the standard, and its implementation into Overseer can be found here. Queries about the standard, and certification options should be addressed to AsureQuality.
Crops which meet the grass-fed standard include plantain, chicory, fodder beet, brassicas (such as kale, turnips, swedes, rape) and legumes (such as clover and lucerne). It also includes cereal grain crops (e.g., Maize, Wheat, Rice, Barley etc.) in the vegetative (pre-grain hardening) state.
In OverseerFM, crops that meet the grass fed standard are all those withing the Fodder, Forage, Pasture seed and Permanent pasture categories:
| Fodder | Forage | Pasture seed | Permanent Pasture |
| Fodder Beets | Annual Ryegrass | White clover | Pasture |
| Kale | Forage Barley | Cocksfoot | |
| Rape | Maize silage | Plantain | |
| Swedes | Forage oats | Ryegrass | |
| Turnip Bulb | Forage wheat | ||
| Turnip Leafy | Forage ryecorn | ||
| Forage triticale |
*Cereal grain crops / silages are considered to be part of a grass-fed diet only when they are in their pre-vegetative state i.e. have not yet produced hardened grains, or the grains have been harvested (removed so not available for consumption)
